Spin properties of single-molecule magnet of double-decker Tb(III)-phthalocyanine (TbPc2) on ferromagnetic Co film characterized by spin polarized STM (SP-STM)
We demonstrate a direct visualization of the magnetic hysteresis of a single-molecule magnet bis(phthalocyaninato)terbium(III) (TbPc2) adsorbed on the Co islands, which covers a submonolayer region of an Au(111) surface by utilizing the spin-polarized scanning tunneling microscope (SP-STM) and monit...

| description | We demonstrate a direct visualization of the magnetic hysteresis of a single-molecule
magnet bis(phthalocyaninato)terbium(III) (TbPc2) adsorbed on the Co islands,
which covers a submonolayer region of an Au(111) surface by utilizing the spin-polarized
scanning tunneling microscope (SP-STM) and monitoring the magnetotunneling resistance. We
found that the TbPc2 molecule is spin polarized and attached to the
ferromagnetic Co islands. The result of the SP-STM measurements showed that the spin of
TbPc2 is antiferromagnetically coupled to the magnetization of the Co island.
In addition, we found an opening in the hysteresis curve even with the frozen
magnetization of the Co island, unlike that with near-zero remanence typically reported
for the bulk crystal and the nonmagnetic substrate. |
